Two groups of rhesus macaques (Macaca mulatta) housed in rodent-controlled outdoor corrals were inoculated with two different encephalomyocarditis virus (EMCV) vaccines. One group (n = 45) received a vaccine made from an inactivated field isolate of virus cultured during an outbreak at a zoo in Florida. This vaccine produced fourfold increases in the titers of 28 animals (62%); the increases persisted for at least 18 months (last test) after a single injection of the vaccine. The other group (n = 51) received a vaccine made from an inactivated porcine field strain of the virus. This vaccine did not produce titers in any of the vaccinees.
